maint: enable sc_prohibit_long_lines

* cfg.mk (local-checks-to-skip): Remove the overall exemption,
but continue to exempt some files in testsuite/.
* configure.ac: Split a long line.
* doc/sed-in.texi: Split long lines.
* doc/sed.texi: Likewise.
* sed/compile.c: Likewise.
* sed/execute.c: Split long lines.
(execute_program): Reorder "#ifdef HAVE_POPEN" and
"if (pipe_fp != NULL)" if/else blocks to make the code
clearer and (incidentally) the lines shorter, due to a
decrease in nesting level.
* sed/sed.c: Split long lines.
* sed/utils.c: Likewise.
* sed/utils.h: Likewise.
